Obama pledges no compromise on timetable

ABC News' Jonathan Greenberger reports: Sen. Barack Obama vowed Sunday night in Iowa that he will refuse to support any troop funding bill that lacks a specific timetable for withdrawal from Iraq.

â€œIf there is a funding bill that does not have a timetable for when we begin withdrawal, and the completion -- a plan for how that withdrawal will proceed -- I will not support it,â€? said Obama during a wide-ranging foreign policy discussion at Des Moinesâ€™ First Christian Church.

Earlier on Sunday, at the Harkin Steak Fry in Indianola, Ia., Obama also promised to work to prevent such bills from becoming law.

â€œWe are going to bring an end to this war and I will fight now in the United States Senate to make sure that we donâ€™t pass any funding bill that does not have a deadline to start bringing our troops out,â€? said Obama.

In so specifically disavowing any such bill, Obama may put himself at odds with some of the Senateâ€™s Democratic leadership, which has talked recently about compromising with Republicans and removing a concrete timetable from the funding bill.

But Obamaâ€™s statement also comes after many of the more liberal members of his party put pressure on him and Democratic frontrunner Sen. Hillary Clinton to be more clear about their opposition to a compromise.

â€œPeople are looking for leadership," said MoveOn.org Executive Director Eli Pariser to ABC News on Friday. "People are happy that they voted against a blank check last time. This time, we want them to speak out sooner and more vocally."
